Introduction
• Determine which chemicals have been used in the system prior to service and regular maintenance. Refer to
Safety Data Sheets for the health and safety precautions that must be followed with chemicals.
• Work in a well-ventilated area.
• Always wear assigned personal protective equipment, including powder-free neoprene or nitrile gloves, safety
glasses, and a laboratory coat.
• Follow required electrical safe work practices.
• Avoid ignition sources when working with flammable materials, such as isopropanol, methanol, and other
flammable solvents.
• Take care in the use and disposal of any chemicals. Potential risk of personal injury if proper procedures for
handling and disposing of chemicals are not followed.
• Avoid skin contact with chemicals during cleaning, and wash hands after use.
• Comply with all local regulations for the storage, handling, and disposal of biohazardous, toxic, or radioactive
materials.
• (Recommended) Use secondary containment trays beneath solvent bottles and the waste collection container
to capture potential chemical spills.
Static Electricity Precautions
Liquid chromatography (LC) uses flammable organic solvents as the mobile phase. LC systems are also often used
where large amount of flammable substances are present. Thus, there is a risk of accidents involving fire or
explosion.
The major cause of these accidents is static electricity. Devising preventative measures for static electricity can be
difficult, because the symptoms before an accident vary and can be hard to detect, because such accidents occur
as a result of several simultaneous incidents. For recommended methods for preventing static electricity accidents,
TM
refer to the Hardware User Guide for the ExionLC system.

Overview
TM
The ExionLC UV Detector is a high-performance, multi-function ultra-violet visible spectrophotometric detector,
for use in high performance liquid chromatography (HPLC). It incorporates both deuterium (D2) and tungsten (W)
halogen lamps. The deuterium lamp is used for ultraviolet applications, as in the PDA Detector, while the tungsten
lamp extends the analytical capability into the visible region.
It has three measurement modes: single wavelength, dual wavelength, and wavelength scanning.
• The dual wavelength mode performs simultaneous detection of two wavelengths, and can provide
chromatograms of both the wavelengths, or a chromatogram of one wavelength and one ratio chromatogram.
• In wavelength scanning mode, the absorbance spectrum is measured. The wavelength scanning mode is
designed to be used while the flow is stopped.

Operating Instructions
Precautions
Precautions before Operation
• Install the flow cell in the detector before turning the power switch on.
If the power switch is turned on with no cell installed, the home position will not be detected and the wavelength
will be set incorrectly. If this occurs, turn the power switch off, install the cell, and then turn the power on. The
cell can be removed after the initial screen is shown.
• Before turning the power switch on, perform any of the following on the flow cell interior:
• Flush the cell with a mobile phase that does not absorb light in the wavelength range of 230 nm or above
(such as water, acetonitrile, or methanol).
• Fill the cell with the above described mobile phase.
• Purge the cell with air or nitrogen, and make sure that it is dry.
When the power is turned on, the module carries out an automatic wavelength accuracy check. The auto
wavelength check uses as a reference the intensity of the emission line wavelengths of the deuterium lamp
(656 nm) and the mercury lamp (254 nm). If a sample that absorbs these wavelengths is used, or if bubbles
remain in the flow cell, the amount of transmitted light becomes exceedingly small. This prevents an accurate
wavelength check from being performed and can produce errors.
• When highly sensitive analysis is necessary, take into account the time needed for the baseline to stabilize and
turn the lamp on ahead of time.
After it is turned on, the lamp requires 1 hour to stabilize for optimal performance.
• Make sure that there are no leaks in the flow cell and connected tubing.
Precautions during Operation
Keep the front cover closed during analysis. In high-sensitivity analysis, opening or closing the front cover will
cause the baseline to fluctuate. The noise level might increase if the front cover is open. Refer to Figure 3-1 on
page 13.

Operating Instructions
Precautions after Operation
To prevent clogging of the flow cell:
• Dusty or clogged flow cells are the most frequent cause of detector problems. After analyzing a highly
concentrated sample, flush the flow cell thoroughly, using plenty of mobile phase. If a buffer solution is used
as the mobile phase, then wash the flow cell with water after completing analysis. Buffer solutions crystallize
upon evaporation, and can clog the flow cell and tubing.
Turn on the UV Detector
• Press the power switch to turn the power on.
The following events occur:
a. All the dots in the status panel screen matrix and all the indicator lamps illuminate.
b. The system performs a memory test.
c. The version number of the control program is shown.
d. The system tests the lamp switching function.
e. The lamps are preheated for 30 seconds.
f. The module is initialized for 1 minute.
g. The wavelength accuracy is checked for 20 seconds, by using the 254 nm emission line of the mercury lamp
and the 656 nm emission line of the D2 lamp.
h. If no error is detected, the message CHECK GOOD is shown for several seconds, followed by the initial
screen.
i. If the D2 lamp has been selected, the screen shown in Figure 5-1 on page 18 is shown. The module
is now in the initial state and is ready for operation.

Operating Instructions
j. If the W (tungsten) lamp has been selected, it is checked and the module goes into the initial state.
Figure 5-2 Initial Screen if the W (tungsten) Lamp Is Selected
Troubleshooting
• If an alarm sounds and a CHECK NO GOOD message is shown on the screen:
a. No peak has been detected within 1 nm of 656 nm or 254 nm. To stop the alarm, press CE.
b. Verify that the cell is installed properly. Refer to Re-install the Flow Cell.
c. Make sure that no air bubbles have been introduced into the flow cell, and that no mobile phase or sample
which absorbs light in the vicinity of 254 nm or 656 nm remains in the cell.
The wavelength calibration function, WAVE CALIB, and wavelength accuracy check function, WAVE CHECK,
measure the intensity of light transmitted through the cell in the vicinity of the 656 nm and 254 nm emission
lines of the D2 lamp and mercury lamp. The module operates based on these intensity values. Consequently,
if a sample that absorbs ultraviolet or visible light remains in the cell, or if large air bubbles are introduced,
the amount of transmitted light becomes exceedingly small and the module will not operate correctly.
Operate using a flow cell that has been flushed or filled with a mobile phase which does not absorb visible
and UV light, or that has been purged of air or nitrogen and dried thoroughly.
d. Execute wavelength calibration, referring to WAVE CALIB in VP Functions.
e. When the calibration is complete, the WAVE CHECK will be run automatically to recheck the wavelength
accuracy. If CHECK NO GOOD is shown once again, turn off the module and contact a representative.
• If an alarm sounds and a NOT PROTECTED message is shown on the screen:
• Press CE to clear the alarm.
When this message is shown, the time program, along with the LAMBDA (wavelength) and certain other
parameters, will be initialized (replaced with default values).
• If any other error message is shown, refer to Error Messages.

Service and Maintenance Information
WARNING! Radiation Hazard. Do not turn on the power while the lamp housing is
exposed to view. You could be exposed to harmful ultraviolet rays.
WARNING! Hot Surface Hazard. Before replacing a lamp, turn off the power and
allow sufficient time for the lamp to cool thoroughly. A hot lamp will cause burns.
CAUTION: Potential System Damage.
• Be careful that the lamp does not
break.
• Do not shake the lamp.
CAUTION: Potential Wrong Result.
• When replacing the lamp, be careful not to get any dust or stains on the mirror surfaces,
D2 lamp, filter surfaces or tungsten lamp. If these surfaces become dirty, accurate
analyses will not be possible.
• Be careful not to touch the glass parts directly with your hands when replacing the
lamp. Wrap the lamp in cotton gauze when carrying it.
• When the lamp is dirty, wipe it with lens paper soaked in ethanol.
The UV Detector has a deuterium (D2) lamp and a tungsten (W) lamp. The lamps must be replaced periodically.
As the D2 lamp and W lamp in this detector approach the end of their life, their intensity decreases and baseline
noise increases. Replace the lamps with new ones using the life ratings listed below as a guide.
Table 6-1 Lamp Life Ratings
Lamp name
Lamp life ratings
D2 (deuterium) lamp
about 2,000 hours
W (tungsten) lamp
about 2,000 hours*
*About the guaranteed life of the W lamp
According to the manufacturer, the life rating for the W lamp is defined as the average lifespan of numerous lamps.
Understand that, depending on the individual lamp, it might burn out before reaching the 2,000-hour life rating.
The guaranteed life of the W lamp is 1,200 hours. The lamp can be replaced free of charge if it burns out before
reaching 1,200 hours of use.
